Product Q&A

Q:What is the MOQ?

The minimum order quantity is 1 set.

Q:What is the lead time for delivery?

Lead time varies by size and type. Nitriding single screws take 40-70+ days, parallel twin screws 45-60+ days, and conical twin screws 35-60+ days. Bimetallic screws require an additional 5 days.

Q:What is the lifespan of the screw and barrel?

Lifespan depends on the formula and heat treatment. For 30phr nitriding, expect 3-5 years. Bimetallic screws and barrels have an extended lifespan.

Q:Can I improve the current screw and barrel properties?

Yes, our engineers can revise or redesign your screw and barrel to improve output or melt quality. Customized solutions are available.

Q:How can we ensure your quality?

We provide test reports for material, heat treatment, and tolerance before shipping. We are ISO9001 certified and partner with many extruder makers in Europe and Asia.
